4This invention relates to means for effecy tively securing building finishing blocks or slabs to Vbrick or concrete supporting walls. 'It sometimes happens, particularly in the case of artificial building slabs', that great diiliculty is encountered in selecting a cement that will effectively bindthe slab to a supporting wall of kbrick or concrete. This is particularly true in the case of slabs of building material made in imitation of stone. In order to guarantee an efficient binding connection betweeny the supporting wall and the blocks or slabs which are to constitute the finished surface (either interior or exterior) I have devisedpan eilicient means in the form of an anchor on the back of the slab or block, which `is so constructed as to not interfere with package or shipment by requiring more room than would be occupied by said slab or block itself, and which, is of such a character that a Workman can instantly put it in condition to function as an efficient anchoring means.

In the drawings I have shown my Vinvention in certain preferred forms, and in said drawings- Fig. 1 is a perspective view of the` rear side of a portion of a'slab of buildingsmaterial which is designed to-forml the finished surface of the building, be it either interior or exterior;

Fig. 2 is a cross section showing my invention as in use;

Fig. 3 is a rear elevation of part of a slab with a modified form of anchorage means;

Fig. el is a cross-sectional modification.

1 represents an ordinary building wall which, in this instance, may be assumed to be of brick. 2 represents aslab of building material whichis to constitute the finished facing for the wall 1. 3 represents a portion of cement by which theslab 2 is secured to the wall 1. At the back. of each slab 2 I may provide one or more anchorage devices which, in the form shownvin Figs. 1 and 2, may comprise a strip 4 of metal, properly secured at one end to the back of the slab 2, as by a fastening 5.,` 6 isa slot in the other end of the strip 4, and 7 is a stud ,secured to the slab 2 and standing in the slot 6. ,.7 v.

When the material Vis onthe ground ready to be installed the workman merely inserts the end of a screw driver or other suitableV tool under the strip 4, between the fastenings 5 and 7,- and deformed or displaced after the manner shown'at thefright hand end of Fig. 1, forezianiplc, thereby forming anoii'setloop. yllhen these anchorage devices 4are deformcdin this manner, a por.

tien of cement is applied `to the back of the slab 2, so as to envelop each anchorage device, and then the slab is placedin position, as indicated in Fig. 2. Manifestly, the cement should be of a character that will adhere firmly to the rough supporting wall,

and,` even ifvit is not of a character` that will by reason of the deformable character of the loolps 4, so as to produce a plumb finished wa Inl the form shown in Fig. 3 I have shown at 4a a modification of the anchorage device' in which, instead of being made of a strip of metal, said device is made of a wire bent intothe form of the figure 8 and secured to the back of the finishing slab 2a by means of a staple or other vsuitable fastening 8. This anchorage will normally lie substantially fiat againstthe back of the'slab, and thus not interfere with packing or shipment. When it is on the ground, ready for setting up on a supporting wall, the looped ends of this modified form of anchorageareV pried up and away from the back of the slab 2 by means of a suitable-toohso that a portion of cement may be applied to and around the anchorage. in place on the supporting wall, it will be mechanically tied thereto, as in the previous case.

purpose ofk my invention is to provide an anchorage device in connection with a block or slab of building material which, when not in use, lies substantially flat against the `rear Whenv the block or slab lis Broadly speaking, it will be seen that the through the medium of said cement and said anchorage, the block may bevery firmly united to a supporting wall.

In the modification shown in` Fig. 4.-*it will be noted that the block 2 is recessed at the backunderncath the strip 4, so that the cement material 3 may flow in under said anchorage strip to lock the block in place. In this particular instance, the anchorage strip 4a may or may not be bendablen to an offset position as shown in Fig. 2.

What I claim is:

1. A piece of building material, an anchorage device secured thereto and fiat against the back thereof, and comprising a strip of sheet metal slidably connected at one end thereto7 said device being displaceable toppermit the same to be envelopedin cement or the like, Said anchorage device being in the A an anchorage for cement.v
